This log gives a section of the rocks overlying the Trenton limestone in the Smithfield dis- 
trict in Wayne County. The format ions below the drift (Pleistocene) are Niagara limestone 
and shale (Silurian), Cincinnati and Utica shale, and Trenton limestone (Ordovician). 
Record of well in the SW. J NW. J sec. 22, T. 20, R. 11 (well No. 25 on H. K. Lewis's farm).

387. AVell near Loogootee, Martin County. 
[Weirbegun June 28, 1905; completed July 15, 1905. Authority, C. O. Potter, driller. Samples pr< • 
served. Geologic correlations by G. II. Ashley.] 
This record gives a section at one of the few gas and oil pools in Indiana that occur i i 
other rocks than those of the Trenton group. The pay sand in this, the Loogootee pool, hi a 
been referred to the Devonian and called the equivalent of the Onondaga (Corniferous) k 
New York. This, however, is clearly impossible, since, according to a section across sout i 
era Indiana, given in the twenty-sixth annual report of the State survey, the stratigraph « 
equivalent of the Onondaga must lie over 1 ,200 feet below the surface at Loogootee . Almc i 
as wrong is its correlation as "Huron, Kaskaskia in part," since the Kaskaskia was prohab j 
passed through within the first 200 feet. The pay sand is referred to the top of t 
Knpbstpne formation of the Mississippian series of the Carboniferous system.
